For millions of East Africans, sending money across town has become almost effortless. A few taps on M-Pesa in Kenya, Airtel Money in Uganda, MTN MoMo in Rwanda, or Mixx by Yas in Tanzania, and the money arrives in seconds.
Try sending that same money across an East African Community (EAC) border, however, and the experience changes.
The transfer may cost more. It may take longer. In some cases, it isn't even possible directly without using a bank, a remittance service, or another intermediary.
That disconnect is becoming harder to ignore. East Africa has spent nearly two decades building one of the world's most successful mobile money ecosystems, yet moving money between neighbouring countries remains far more complicated than moving it within them.
The interesting part is that this is no longer a technology problem. The infrastructure to move money already exists. The bigger barriers are regulation, interoperability, and the way different financial systems continue to operate within national borders.
A Region That Already Solved Domestic Payments
Before looking at the gaps, it's worth recognising how much East Africa has already achieved.
Across the region, mobile money has become everyday infrastructure.
In Kenya, M-Pesa processes billions of dollars in transactions every year and has become the default payment method for individuals, merchants, and businesses alike.
Uganda's MTN Mobile Money and Airtel Money dominate everyday transactions in much the same way. Tanzania's mobile money market is shared between Mixx by Yas (formerly Tigo Pesa), M-Pesa, Airtel Money, and HaloPesa, while Rwanda has built a similarly mature ecosystem around MTN MoMo and Airtel Money.
Across these markets, paying salaries, school fees, utility bills, transport fares, and small business suppliers digitally has become routine rather than remarkable.
That maturity has allowed fintech innovation to move beyond payments into lending, insurance, and investment products through embedded financing.
Tanzania also demonstrated what interoperability can look like. Since 2021, customers using different mobile money providers within the country have been able to transfer funds directly between wallets without worrying about which network the recipient uses.
It is exactly the kind of experience users increasingly expect.
Where the Experience Breaks Down
The problem starts the moment money crosses a border.
A Kenyan using M-Pesa still cannot send money as easily to someone using Mixx by Yas in Tanzania as they can to another M-Pesa user in Nairobi. Even when cross-border transfers exist, they often involve additional fees, multiple intermediaries, or longer settlement times.
For users, it feels inconsistent.
For businesses, it becomes a genuine obstacle.
The irony is that the countries involved belong to the same regional bloc, trade with one another every day, and have spent years promoting economic integration.
Yet their payment systems remain far less connected than their roads or transport networks.
Why Crossing Borders Is So Much Harder
The obvious explanation is technology.
The real explanation is regulation.
Each country has its own anti-money laundering (AML) requirements, know-your-customer (KYC) standards, foreign exchange rules, consumer protection laws, and licensing frameworks.
Those rules do not automatically recognise one another simply because countries belong to the East African Community.
Currency adds another layer of complexity.
A payment moving between Kenya and Tanzania involves the Kenyan shilling and the Tanzanian shilling. Depending on the payment corridor, settlement may still involve international banking systems and reserve currencies like the US dollar, introducing additional costs and delays into what is, geographically, a short-distance transfer.
In other words, the challenge isn't moving the money.
It's agreeing on how it should move.
Why It Matters More Than It Seems
For consumers, the inconvenience is obvious.
For businesses, the cost is much larger.
Small and medium-sized enterprises increasingly buy inventory, hire suppliers, and sell products across East African borders. Every additional payment fee, settlement delay, or reconciliation challenge adds friction to regional trade.
Cross-border payments also matter for workers.
Thousands of East Africans live, study, or work in neighbouring countries while supporting families back home. Sending money across the region should, in theory, feel almost as straightforward as making a domestic transfer.
Instead, it often resembles an international remittance.
That gap becomes even more significant as regional trade continues to grow under the African Continental Free Trade Area (AfCFTA).
If moving goods across Africa becomes easier while moving payments does not, businesses still face a major constraint.
The Infrastructure Taking Shape
The encouraging news is that solutions are already being built.
One of the most significant is the Pan-African Payment and Settlement System (PAPSS).
Rather than routing payments through correspondent banks outside the continent, PAPSS aims to allow businesses and financial institutions to settle transactions directly in local currencies.
That reduces dependence on foreign currencies while lowering settlement costs and processing times.
The African Continental Free Trade Area is also creating political momentum.
Removing trade barriers becomes far more meaningful when businesses can pay suppliers across borders without unnecessary friction. Payments and trade are increasingly being viewed as two parts of the same problem.
Regional organisations such as COMESA have also been working on payment integration initiatives designed to improve financial connectivity across member states.
None of these efforts will produce overnight results.
But together, they represent an important shift away from isolated national payment systems toward genuinely regional financial infrastructure.
The Next Challenge for East African Fintech
The first chapter of East African fintech was about proving digital payments could replace cash.
That chapter has largely been written.
The second has focused on building services such as lending, insurance, and investment on top of those payment rails.
The third may be about connecting those rails across borders.
Cross-border payments remain one of the least developed parts of the region's fintech ecosystem despite their enormous economic importance.
For startups, banks, and regulators alike, solving this problem could unlock entirely new opportunities in regional commerce, SME financing, remittances, and digital trade.
Progress Will Be Gradual
There is no single announcement likely to solve cross-border payments overnight.
Building interoperability across multiple countries requires regulators, central banks, telecom operators, payment providers, and commercial banks to align around common standards.
That takes time.
The good news is that many of the technical foundations already exist.
The harder work is institutional rather than technological, creating rules that allow different payment systems to trust one another while protecting consumers and maintaining financial stability.
Progress is therefore likely to come corridor by corridor rather than across the region all at once.
The Next Infrastructure Story
Domestic mobile money transformed how East Africans move money.
The next transformation is unlikely to come from another wallet app or payment platform. It will come from making national payment systems work together as seamlessly as they already operate within their own borders.
Like many infrastructure challenges, cross-border interoperability is not especially glamorous. It won't generate the excitement of a new fintech launch or a billion-dollar funding round.
But once it is solved, it will probably feel obvious in hindsight.
The same way sending money across a city now feels routine, sending money across an East African border should eventually feel no different.
That may become the next defining chapter in East Africa's digital payments story.
